ABSTRACT

A commissioning system ( 1 ) is provided with product storage compartments ( 2 ) vertically to horizontally disposed in a shelf, in which products are stacked. The product right at the bottom of such a stack of a selected product storage compartment can be ejected by a positionable ejector unit ( 4 ) in a direction transverse to the shelf. The inventive system is further characterized in that the shelf ( 5 ) is configured as a frame/component system, especially as a frame and plug-in modules system, which comprises modular elements. The shelf is variable in terms of height, width and/or length and can optionally be extended by adding modular elements.

FIELD OF THE INVENTION

The present invention pertains to a commissioning device with productstorage units arranged in positions ranging from vertical to horizontal,in which products are stacked, arranged one on top of another or next toeach other in a row, wherein the product of a selected product storageunit, which product is the lowermost or frontmost in the stack, can bepushed out in the transverse direction of the shelf by a positionableejector unit or push-out unit.

BACKGROUND OF THE INVENTION

A commissioning device of the above-mentioned type has been known from,e.g., EP 0 403 726. The shelf is preferably designed as a double shelfback to back, is gently sloped to the vertical, and has an A-shapedfront view, and a longitudinal conveyor belt is arranged at least at thebase of the “A”, and a plurality of push-out planes may be provided atdifferent levels, with which additional longitudinal conveyor belts maybe associated.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a commissioning deviceof the type mentioned in the introduction, which has a simple design andcan be used in various variants in a versatile manner and ischaracterized, in particular, by simple and rapid mounting of the shelf.

The essence of the present invention is that the shelf is provided as aframe components system, especially as a plug-in frame system and itcomprises modular individual components, and the shelf can be builtvariably in terms of height, width and/or length and can be optionallyexpanded by attaching additional modular individual parts.

The shelf is preferably composed of at least four vertical supports ofidentical design, a plane that can be suspended and at least two crossstruts of identical design, which can be brought into a preferablypositive-locking plug-in connection with the vertical supports in aselected position, as well as at least one longitudinal strut, and ithas at least one guide rail, on which the push-out unit is guidedmovably along the shelf at a selected product storage unit and isfastened. If this design variant is based on the above-mentioned minimumnumbers of pieces for vertical supports, cross struts and longitudinalstruts, this leads to the simplest form of a commissioning device in theform of a shelf module with integrated guide rail and a push-out unit,which makes commissioning possible in one push-out plane in the case ofa plurality of product storage units arranged in a row in the shelf. Theabove-mentioned individual parts of the shelf form a sufficiently stablestructure in the mounted state of the shelf including the guide rail anda plurality of product storage units.

In the case of longer vertical supports, the aforementioned shelf can beexpanded upward with additional cross struts and longitudinal struts andadditional guide rails with additional push-out units at equal overalllength. At least one second push-out plane, which can be operatedindependently from the first push-out plane, is embodied in this case,without the push-out units interfering with one another during theirlongitudinal movements during commissioning.

However, the shelf can also be expanded in its overall length, which isachieved by attaching additional vertical supports, cross struts andlongitudinal struts. The guide rail is extended in this case by anextension piece or, which is better for the stability and the functionof the entire system, by a correspondingly longer guide rail, on whichat least one push-out unit is longitudinally displaceable. Commissioningin one push-out plane is now possible over a greater length at a largernumber of product storage units.

It is apparent that the above-mentioned expansion of the shelf in termsof height and length and optionally width according to the modularprinciple may be continued, in principle, up to commissioning units thesize of a shop, where it is possible, e.g., not only to embody manypush-out planes in height, but even to set up a second or third operatorplane on the side of the high shelf for a person to walk on.

It is especially advantageous for the shelf to additionally comprise afastening rail with a longitudinal conveying means extending in thelongitudinal direction of the shell, especially with a longitudinalconveyor belt, on which a commissioned product pushed out by thepositioned push-out unit can be given out and removed. In this case, thecommissioned products do not fall under the shelf into a container madeready, especially in case of a short overall length of the shelf, butthe products, sorted according to commission or according to an order,are conveyed to a remote location, depending on the local individualconditions.

Longitudinal conveyor belts may be provided in different push-outplanes. In particular, a separate longitudinal conveyor belt may beassociated with each push-out plane.

At least the vertical supports, the cross struts, the longitudinalstruts and the push-out unit are preferably modular individual parts,which may also be used multiply in various sizes or lengths within theframework of a comprehensive modular system to individually shape acommissioning device, and, in particular, a layman or the user of acommissioning unit can also install especially the shelf of thecommissioning device for the most part himself in a reliable manner andin a short time.

An especially advantageous commissioning device is characterized in thatat least one additional shelf is connected to a shelf, which is providedwith a guide rail, a push-out unit, a buffer storage area and optionallya longitudinal conveyor belt as a so-called commissioning shelfaccording to the frame components system, especially the plug-in framesystem, preferably in a plug-type connection, or such an additionalshelf is associated with the shelf, the additional shelf being designedas a so-called non-commissioning shelf without push-out unit andpreferably also without product storage unit, without guide rail andalso without longitudinal conveyor belt, and having, instead, flat shelfbottoms arranged preferably on the cross struts, preferably at adifferent level, on which bottoms products can be arranged,intermediately stored and handled. Such a commissioning deviceconsequently comprises individual parts, many of which are of anidentical structure and consequently have the same optical appearance,and individual shelves are commissioning shelves and other shelves arenon-commissioning shelves basically in the form of storage shelves whichare known per se, but are built according to the modular principleaccording to the present invention.

Such non-commissioning shelves can be made according to the presentinvention into a commissioning shelf with especially simple means, i.e.,they can be converted if the user so desires. Only the flat shelfbottoms must be removed in this case, the product storage units areinserted instead into the modular basic frame comprising theabove-mentioned vertical supports, cross struts and longitudinal struts,and the push-out units are installed, optionally also with guide railsand longitudinal conveying means, unless they are already installed in anon-commissioning shelf.

Likewise, commissioning shelves can preferably be converted according tothe present invention into additional shelves, i.e., intonon-commissioning shelves with simple means if the user so desires.Consequently, a user can, e.g., expand an already installed, smallcommissioning unit comprising a few commissioning shelves and a fewnon-commissioning shelves practically as desired, and the function ofthe non-commissioning shelves can be changed to that of commissioningshelves to expand the capacity of the entire unit, without the basicstructure and the site of fastening of the unit having to be changed,doing so with astonishingly simple and consequently inexpensive means.If, furthermore, the user wishes to change the function of existingcommissioning shelves, so-called dynamic shelves, into that ofnon-commissioning shelves, so-called static shelves, this is likewisepossible according to the present invention with simple and inexpensivemeans. Consequently, the user sees that the present invention offerspractically any desired variety of variants and any desired possibilityof shaping one or more commissioning units with very simple means.

It is highly advantageous for the vertical supports to be stable andalso lightweight profile strips that can be manufactured at a low costwith holes located preferably at equal distances from one another, inwhich end-side hook elements of the cross struts can be suspended,preferably in a positive-locking manner.

The profile strip has, especially in its cross section, a U shape, andboth the base and the two legs of the U-shaped profile strip havepreferably equidistant holes or openings for suspending a cross strut ora longitudinal strut. Such a profile strip is, aside from the length,which corresponds to the height of an individual shelf of thecommissioning device and can be optionally cut to size correspondinglyby cutting—is a universal strip, which can be used for both an angularcorner connection of a shelf frame and a flat T-shaped extensionconnection of a shelf frame.

The cross struts may optionally also be bolted to the vertical supportsand/or fastened or secured by securing pins, and the longitudinalstrut(s) may likewise be preferably firmly fastened, especially bolted,to the cross struts. The stability of the shelf results from theassembly and optionally final bolting together of the individual parts.

The product storage units can be fastened at the cross struts and/orlongitudinal struts, especially by means of a plug-in connection.

The product storage units themselves may be designed as magazines thatcan be fitted together, with a bottom-side product support and at leasttwo side walls located at spaced locations from one another, which arepreferably essentially vertical angle sections. The magazines may havedifferent heights.

The distance between the spaced-apart side walls of the magazine, whichcan be fitted together, can be set to or coordinated with the width ofthe product, and the product width set or a plurality of product widthsset preferably correspond to the horizontal distance between twoadjacent cross struts. The aforementioned distance also corresponds tothe length of one shelf module, comprising mainly the above-mentionedmodular individual parts.

The product storage units, arranged in a longitudinal row, arepreferably sloped relative to the vertical direction for an obliquelydownwardly directed pushing-out movement of a product, which is thelowermost product in the stack, in the transverse direction of theshelf.

The cross struts may be arranged at different levels, and everyindividual level defines a push-out plane with associated productstorage units, guide rail and push-out unit, and a separate longitudinalconveying means extending in the longitudinal direction of the shelf maybe associated with each push-out plane.

A cross conveying means for the product, which is a rigid part of theshelf and is preferably a chute, and an ascending belt or a bufferhopper, may be provided between the push-out opening of the productstorage unit and the longitudinal conveying means.

The push-out unit is preferably arranged in a suspended manner andlongitudinally movably at the guide rail, and a plurality of push-outunits may also be provided at a single guide rail.

The push-out unit has at least one push-out means for pushing out thelowermost product of the stack of a selected product storage unit in thetransverse direction of the shelf, and it optionally has a separate,activatable longitudinal drive as well as a separate, activatable crossdrive for the push-out means, and the longitudinal drive may also befastened to the shelf and may be connected to the push-out unit via adrive, preferably a toothed belt drive. A chain or a V-belt drive mayalso be considered.

Furthermore, the push-out unit is supplied with electricity from abattery or via electric sliding contacts and a conductor rail arrangedon the longitudinal side of the shelf.

The activation of the push-out unit, which is necessary forcommissioning, is performed by means of a data light barrier, radio orby modulation from the conductor rail.

The shelf may be designed as a double shelf with at least one middleguide rail and at least one middle longitudinal conveying means, inwhich case the push-out unit has two preferably identical push-outmeans, which have a mirror-inverted design relative to the verticallongitudinal central plane of the double shelf, and each push-out meansis associated with one half of a double shelf.

A plurality of shelves and/or double shelves may be arranged in parallelto one another and/or opposite one another, and each outlet of alongitudinal conveying means located on the longitudinal side of theshelf may be connected to a collecting conveying means, which preferablyextends at right angles to the longitudinal conveying means and ispreferably a central conveyor belt of shelves arranged opposite eachother or a lateral conveyor belt of shelves arranged in parallel. Shelfrows may also be arranged one behind another.

A connecting conveying means, especially an ascending belt, a chute or abuffer hopper may be optionally arranged between the outlets of thelongitudinal conveying means and the collecting conveying means. Thelongitudinal conveying means and/or connecting conveying means maycontain activatable product stoppers that can be actuated.

The shelf or shelves may have at least one walkable operating platform,which may be preferably arranged at a different level laterally from theshelf and/or at the longitudinal end of the shelf, preferably by meansof a plug-in connection.

In addition or as an alternative, the shelf or shelves may have at leastone shelf ladder for a human operator, which can be laterally displacedor suspended.

The guide rail comprises, in particular, at least at one longitudinalend of the shelf, an openable stop for a longitudinally movable push-outunit, preferably a guide rail piece that is pivotably articulated to theend of the guide rail and that forms a stop in a transverse position forthe push-out unit on the guide rail and releases the push-out unit in apreferably aligned longitudinal position, and especially establishes aconnection to a service site or exchange site for push-out units.

The push-out unit in the form of an ejector vehicle comprises a motorwith a corresponding transmission and drive system for moving theejector vehicle along the guide rail, e.g., by means of a belt system. Aplurality of ejector vehicles per plane may be used simultaneously.

The drive motor may also be arranged externally on the shelf frame.

Variable, adjustable magazines may be used as product storage units, asthey are described, e.g., in AT Patent No. 404124. The product storageunits are arranged laterally in parallel to one another in thelongitudinal direction of the module.

The data transmission/communication may take place via a data lightbarrier with or without order data buffering, radio or by modulation bymeans of the energy supply.

The function will be described below.

After the transmission of an order with n positions and n ejections perposition via the data light barrier or another of the aforementionedpossibilities of transmission to the ejector vehicle, the latter startsout from the order start position into the first order position.

The products are ejected from the product storage unit into the middleof the aisle by means of the studded belt on the ejector of the ejectorvehicle. The products drop onto the conveyor belt by a limited, definedfall by means of the cascade plates. Depending on the design, theproducts are pushed via this conveyor belt onto a central belt in adirectly order-related manner or they are pushed together onto a shortarea of the conveyor belt by means of a buffering device and are thenconveyed onto a central belt or collecting belt in an order-relatedmanner.

Instead of onto a central belt, the products may also be transferreddirectly into the container via a buffer hopper in an order-relatedmanner.

After the end of the travels needed for handling the orders, the ejectorvehicle returns into its order start position. This return travel to theorder start position depends on the variant of the data transmissionused and can be avoided or optimized to increase the throughput.

The control of the shelves as well as the higher-level control areperformed by means of software.

The arrangement is such that the automatic system may be arranged as asingle aisle, as a system of n aisles in an overall system design withmaterials handling connections and in connection with othercommissioning systems.

The product storage units are refilled manually, but the refilling mayalso be performed automatically corresponding to the design of theproduct storage unit.

The modular design makes it possible to replace individual parts of theframe system, the commissioning system and the materials handlingtechnology in a simple manner. Furthermore, it is possible to remove theejector vehicles from the system of planes by means of a variable driveand installation system and to replace them with a replacement vehicle.

Consequently, a plurality of vehicles can eject products from aplurality of planes independently from one another. The modular plug-insystem of the shelf is suitable for modularly receiving other types ofautomatic units. Rapid, simple replacement of the vehicle, whichcontains most of the drive mechanism and the control technology, ispossible.

The various features of novelty which characterize the invention arepointed out with particularity in the claims annexed to and forming apart of this disclosure. For a better understanding of the invention,its operating advantages and specific objects attained by its uses,reference is made to the accompanying drawings and descriptive matter inwhich a preferred embodiment of the invention is illustrated.
